I’m in Texas and I buy the canned salmon at HEB. It’s a generic brand, says pink salmon on the can. It does look like fish chum, ground up chunks w/ bones, but it’s for people and I use the recipe on the back of the can, substituting oats for the cracker crumbs. I find it around where the tuna is sold. Scooby’s Workshop had a recipe where you fix a big batch of lentils & mix w/ salmon. I tried it and thought it was pretty gross, especially after eating it a few times. The salmon patties are actually good, it was hard not to eat more than one yesterday.
